Virtual reality technology based remote control system and remote control method for coal cutter

Abstract

The invention discloses a virtual reality technology based remote control system and a remote control method for coal cutters. The system comprises a control platform, an underground industrial control bench, an underground controller, an external hardware and virtual software data interface and a virtual working platform; and the control platform comprises a remote manipulation device and a data acquisition module. The remote control method comprises: a control instruction emitted by the remote manipulation device is received by the underground industrial control bench, and the underground controller drives three underground devices to work; the working state data of the three underground devices is acquired on a real-time basis and processed; and the data acquisition module uploads the data to the control platform. Meanwhile, a control instruction emitted by the manipulation device is acquired by the hardware and software data interface and sent to the virtual working platform; an internally compiled program completes the driving of a virtual prototype; in addition, the control platform also sends the working state data of the three underground devices to the virtual working platform on a real-time basis for correction on the virtual prototype and realization of synchronous operation of the three underground devices and the virtual prototype, thereby completing remote monitor on the coal cutter. The invention has reasonable design, strong practicality and high value for popularization and application.

Description

technical field [0001] The invention relates to the technical field of remote monitoring, in particular to a remote control system and method for a coal mining machine. Background technique [0002] Shearer is the main mechanical equipment in coal production, which determines the production efficiency of fully mechanized mining face. Although the shearer control system has the functions of monitoring and fault diagnosis, because coal mining is a typical complex time-varying system, especially in the coal mining face, there are many equipments and complex space environment, in which many factors of human, machine and environment are intertwined. Parallel occurrence, so that the staff can not timely control the various operating parameters of the coal mining machine, therefore, to realize the automation of the fully mechanized mining face has become a focus of research in the field of coal mines, and the remote control system of the coal mining machine is an important part of ...

Although the shearer control system has the functions of monitoring and fault diagnosis, because coal mining is a typical complex time-varying system, especially in the coal mining face, there are many equipments and complex space environment, in which many factors of human, machine and environment are intertwined. Parallel occurrence, so that the staff can not timely control the various operating parameters of the coal mining machine, therefore, to realize the automation of the fully mechanized mining face has become a focus of research in the field of coal mines, and the remote control system of the coal mining machine is an important part of it

At present, there is no mature remote control system for coal mining machines in China. Most coal mines generally adopt the method of installing cameras for remote monitoring. Due to the complex and harsh working environment of coal mining machines, the image collected by the camera is often unclear, which brings great difficulties to remote control. It is very difficult; or use the shearer controller to monitor the current, voltage, speed, temperature, rocker angle and other parameters of the shearer when the shearer is running, and directly display the parameters or carry out graphical modeling display, and the shearer staff will carry out Operate and monitor the working status of the shearer in real time

However, due to the unintuitive display method of the monitored operating parameters of the shearer, it is difficult for the staff to accurately judge the working status of the shearer, so this control method also has great disadvantages
